I don't think Roxsquad ever played organized Basketball. It's a team unity sign. We did it thru HS and all other teams I played for after.
I played through high school, and we didn't play pattycake at the freethrow line. I understand why they are doing it, we just didn't do it at the line. We would say something to the player as we went back down the court. We also wore shorts not skirts, and everyone on the team could make a mid range bucket.
